So you wouldn't have a problem if abortion protesters had government agents take their photos outside of an abortion clinic? Of course the photos would be turned over to the FBI, you know because religious freaks bomb clinics. So it's just a precautionary measure they're taking when they review their IRS records, bank accounts and on-line accounts. Do you see how this can get out of hand? Or do you agree with Hillary's review of the FBI files?
You don't think this already happens? Especially in light of abortion clinic bombings?
Friend, when you go out in public, anybody can snap your picture. This is a free country. Now when they do something bad with it that is another story.
The authorities, lately have learned that pictures and video can often keep them from frivolous attacks by lawyers making all kinds of claims. Pictures talk in court.
My point is, that if you are going to protest, you should expect that your picture will be taken and very likely to be used by the media or if your are in a melee, by the courts.
